EMPrD02^AX TRAILLI, (Aud.) Bd. 



TrailVs Flycatcher. 



I have not distinguished between the two species of this bird — var. traiUii and var. 

 pttsilluy — but my impression is that the latter is the most abundant of the two, though 

 I have only occasionally met either one. I have made no dissections and only assign 

 them to the list of locust-eating birds from the known characters of their congeners.

Least FlycatcTier, 



Eather common in Nebraska, and occasionally breeds in the northeastern portion of 

 the State. I only examined a few specimens in 1865 and 1866.

Empidoxax flaviventris, Bd. 

 YeUoiv-dellied FlycatcTier. 



This bird occurs sparingly in Eastern Nebraska, and have known it to breed on the 

 skirts of timber belts along the IMissouri. The only one that I dissected was obtained 

 in July, 1870, near Dakota City. It had 16 grasshoppers among the insects in its 

 stomach.

Antrostomus vociferus, (Wils.) Bp. 



WMjJipoonvill. 



Occasionally found in Eastern Nebraska, where it breeds. In August, 1867, when 

 encamped on the Bow Eiver, in Nort^ieastern Nebraska, during a locust invasion, I 

 shot two of these birds. Each had its stomach crowded with locusts. I have dis- 

 sected no others. 



Antrostomus nuttalli, (Aud.) Cass. 



NuttalVs WTiippoorwill. 



Eather common in Central and Western Nebraska, in the vicinity of timber. Occa- 

 sionally seen further east. In August, 1869, when camped on the Bow Elver, in North- 

 ern Nebraska, on a moonlight night, I was kept awake by one of these birds. Having 

 long desired to secure one, I crept out toward the place from which the sound of "poor' 

 will" issued. On the wing I shot the bird, and the next morning I found that four- 

 fifths of the contents of the stomach were composed of grasshoppers and locusts
